‘A Case of You’ is a Facebook romance with little to like

A Case of You

A general rule of romantic comedy is that the hero — the lovestruck schlemiel chasing the girl of his dreams -- should be likable. The problem with “A Case of You” is that not even the movie likes him.

Justin Long has no one but himself to blame: He co-wrote the archly self-conscious script and stars as Sam, a mopey Brooklyn writer in love with the barista next door. Her name is Birdy (Evan Rachel Wood) and she’s — surprise — a free spirit. Sam is so insecure that he stalks her on Facebook and gives himself a personality makeover based on her posts and favorite books. You’ve heard of a love story. This is a “Like” story, and it is cringe-y in the extreme.
